Paintings of Love on Valentine's Day

Valentine's Day is important to us all, retailers, restaurateurs , couples & me of course. Was wondering which is the most romantic painting of all time. Nothing specific came to mind.
But many would consider,

The Kiss (1907-1908)  by Gustav Klimt, an Austrian painter, to be such a painting.

The painting displays an embracing couple, surrounded by patterns in the robes. The style was influenced by the arts and crafts movement and Art Nouveau. The mediums are oil and gold leaf on canvas.

The Kiss can be viewed at Österreichische Galerie Belvedere, Vienna.
